Abstract

A method is presented to identify moving forces on a continuous bridge. The bridge is modeled as a continuous supported Bernoulli-Euler beam and the boundary value problem of the beam is solved to get the exact mode shape functions of vibrating beam with inner supports. The bending moment responses are used to study the inverse problem in identifying moving forces on a bridge. The SVD (singular value decomposition) is used in the solution to study the inverse problem. Two time varying forces moving over the bridge are simulated to evaluate the method. White noise is added to simulated bending moment responses to study the effect of noise in moving forces identification problem for different numbers and arrangements of sensors. Results obtained from simulation study show that the method is effective in identifying moving forces and acceptable results can be obtained.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
